What about Paper?

Recycling paper uses less energy, in principle, but what about the net environmental impact? Tough call, says Slate. I've also heard some mumbo-jumbo about paper and how most paper comes from tree farms. Thus, even though a "farmed" tree does not live very long, the carbon-absorption that it contributes kind of tips the scale, although it does not mean we should just zip through paper with reckless abandon.
